Simulation and Prediction of Mine Inflow:a Case Study of Shihao Coal Mine of Henan Yima Coal Group

摘要

The calamities caused by mine water had brought about enormous economic losses and casualties, predicting the mine inflow has been the scientific basis for the management of damage caused by mine water. In this paper, we took Shi Hao coal mine in Henan province as an example, predicted the mine inflow by means of numerical simulation and found that if the mining level reached +100m the mine inflow would be 445.08m3/h.To ensure the safety of coal production, we should make the water discharge to this value or larger than it when designing the drainage of the mine.
